Which of the following is the value of lim_x›7[(x²-2x - 35) / (x - 7)]

Yanıt Açıklaması:

The function is a rational function. Because the limits of the numerator and the denominator are equal to 0, we need to factorise the ratio which follows as

[(x²-2x - 35) / (x - 7)] = [(x - 7) (x + 5)] / x-7 = x + 5.

Following the limit rules, we find lim_x›7x + 5 = 7 + 5 = 12.
